A misconfigured peering connection between two VPCs can lead to instances within those VPCs being unable to communicate with each other, assuming there are no other connectivity options or misconfigurations in place.
Peering connections are set up to enable direct network connectivity between two Virtual Private Clouds (VPCs) within the same cloud provider or across different cloud environments. A peering connection that is misconfigured can block traffic between the VPCs, resulting in instances that are unable to communicate with each other. This assumes that there are no other networking services, like VPNs or direct connects, configured that could also grant network connectivity between the two VPCs.
